Claims

[Scope of utility model registration request]

A failure indicator is attached to a control panel and displays on its illuminated surface the contents shown on an illuminated dial in response to a failure occurring in a plant process. a first light source that irradiates light onto a portion of the illumination surface where the contents of the illumination dial are displayed; and when the failure is a serious failure, a portion of the illumination surface where the contents of the illumination plate are not displayed; A fault indicator having a second light source that emits light of a different color than the first light source.
